Technical Field
The embodiment of the application relates to the technical field of computers, in particular to a method and a device for outputting information.
Background
Data fusion refers to reducing the data volume to the maximum extent on the premise of keeping the original appearance of the data as much as possible (the necessary premise for completing the task is to understand the mining task and to be familiar with the content of the data). There are two main approaches to data fusion: attribute selection and data sampling, for attributes and records in the original dataset, respectively. Assume that data is selected for analysis at the company's data warehouse. So that the data set will be very large. Complex data analysis buckle mining on massive data would take a long time, making such analysis impractical or infeasible. Data fusion techniques can be used to obtain a fused representation of a data set that, although small, substantially preserves the integrity of the original data. In this way, mining on the fused data set will be more efficient and produce the same (or nearly the same) analysis results.

It should be understood that the number of data sources, networks, and servers in FIG. 1 is illustrative only. There may be any number of data sources, networks, and servers, as desired for an implementation.
With continued reference to FIG. 2, a flow 200 of one embodiment of a method for outputting information in accordance with the present application is shown. The method for outputting information comprises the following steps:
In the present embodiment, an execution subject of the method for outputting information (e.g., a server shown in fig. 1) may acquire feature data sets from different categories of data sources that store feature data for the same object by wired connection or wireless connection. The object may be a POI (Point Of Interest), for example, a house, a shop, a mailbox, a bus station, etc. in a map system. The data source may be a source of characteristic data of the object. Such as shopping-like applications, navigation-like applications, etc. The feature data comprises categories, feature names and feature contents. The characteristic content table is used for representing the corresponding relation between the category, the characteristic name and the characteristic content. The key in the key value pair is a feature name and the value is a category. Categories refer to categories of data sources. Such as indoor maps, vehicle life, scenic spots, authoritative data, etc. in the map data. The vertical category refers to a single domain (or region) such as IT, entertainment, and sports. Under each category, there is a feature name corresponding to the category. Such as short comments, labels, subtitles, icons, and the like. The position of the label 2 in fig. 3 shows the correspondence of the category to the feature name. Each feature name has a specific feature content corresponding thereto. And generating a key value pair set and a characteristic content table corresponding to the category for the characteristic data processing of each data source respectively. That is, multiple sets of key-value pairs may be generated, each set of key-value pairs corresponding to a category. A plurality of feature content tables may be generated, each feature content table corresponding to a category.
As an example, the characteristic data may be as follows:
it should be noted that the wireless connection means may include, but is not limited to, a 3G/4G connection, a WiFi connection, a bluetooth connection, a WiMAX connection, a Zigbee connection, a uwb (ultra wideband) connection, and other wireless connection means now known or developed in the future.
Processing the feature data set comprises extracting categories, feature names and feature contents from the feature data. Then the category and the feature name are combined into a key-value pair. And storing the corresponding relation among the category, the feature name and the feature content in a feature content table. The feature content can be found through the category and the feature name. The diversified vertical data can be subjected to standardized management through a unified protocol management layer. And the data access is complied with by each vertical service party. The feature names and the feature contents are detailed data after each category is normalized, and include short comments, tags, state information, sub-point information, yellow tag information and the like.
Optionally, if the category and the feature name in the data source are stored in a manner of a key value pair with the category as a key and the feature name as a value, the key value pair may be directly converted into the key with the feature name as a key and the value as the key value pair with the category. For example, for data in the jason format, the jason key value pair is a way to store the JavaScript object, and is different from the writing method of the JavaScript object. A JavaScript object is a content wrapped { } using curly braces. The key name in the key/value pair combination is written ahead and "wrapped" with a double quote, using a colon: separate, then colon followed by value. For each piece of feature data, the category and the feature name form one group of key-value pairs, and the feature name and the feature content form another group of key-value pairs. The detailed data of each category can be independently mapped, and the mapping process mainly comprises the steps of transposing and extracting the data according to an agreed protocol. The mapping can be to "key" as a category; value is a feature name, namely ' key ' is a feature name, value is a category ', and processing logic related to rules can be added inside the mapping unit to extract data.
In some optional implementations of this embodiment, before processing the feature data set to obtain the key-value pair set and the feature content table, the method further includes: and for the feature data in the feature data set, in response to determining that the feature data does not meet the predetermined check condition, deleting the feature data from the feature data set. Data verification may also be performed prior to data processing. And verifying whether the category, the feature name and the feature content are included in the feature data. If any is missing, the feature data may be deleted.
If different categories have respective short-term data, the original characteristic data is as follows:
the generated key-value pairs:
1. key is "short comment" and value is "Category 1"
2. key is "short comment" and value is "Category 2"
The generated characteristic table is shown in the following table:
| categories | Feature name | Feature content |
| Class 1 | Short | abcdef |
| Class | ||
| 2 | Short comment | uvwxyz |
TABLE 1
In the present embodiment, step 202 includes the following sub-steps:
and S1, extracting categories from at least one key value pair comprising the feature names, and generating a category set corresponding to the feature names. That is, key value pairs with the same key are merged, and the value in the merged key value pair is the various categories corresponding to the feature name.
As shown in the above example, the merged key-value pairs are as follows
And S2, selecting the target category from the category set according to a preset rule. For example, the predetermined rule may be to select only one target category, to select all categories, or to select a limited number of target categories. For example, the category corresponds to the priority, and the category with the highest priority is selected as the target category from the category set corresponding to the feature name. In the above example, if the priority of category 1 is higher than the priority of category 2, category 1 is selected as the target category.
Optionally, in response to determining that the feature content corresponding to the feature name is configured in the data source sharing mode in advance, a predetermined number of categories are selected from the category set corresponding to the feature name as the target categories according to the order from high priority to low priority. That is, the feature data after final merging may use the feature data in the data source of the category 1 or the feature data in the data source of the category 2.
And S3, inquiring the feature content corresponding to the feature name and the target category from the feature content table to be used as the target feature content corresponding to the feature name. For example, if it is determined in step S2 that the target category is category 1, the feature content "abcdef" corresponding to category 1 and "short score" is looked up from the feature content table. The characteristic content is target characteristic content, and can be used for replacing the characteristic content in the characteristic data in other types of data sources. That is, the data corresponding to the target category is synchronized to the data sources of other categories. Optionally, in response to determining that the number of the target categories corresponding to the feature names is greater than the predetermined number threshold, adding the feature content corresponding to each target category queried from the feature content table to the candidate feature content set. And performing clipping processing on the candidate feature content set. And taking the candidate feature content in the candidate feature content set after the cutting processing as the target feature content corresponding to the feature name. The clipping process selects a predetermined number of target feature contents from the candidate feature content set. For example, the target feature content corresponding to the category with the high priority level is selected, or a predetermined number of target feature contents are selected in the order of the number of characters from high to low. Optionally, the feature data may further include data update time, and the target feature content may be selected according to a time sequence from near to far.
And S4, outputting the target characteristic content corresponding to the characteristic name. And outputting the target feature content corresponding to each feature name. The output here may be output to a display in a display manner, or may be output to a medium such as a memory or a hard disk. The characteristic content can be checked before output to avoid outputting the content violating laws and regulations.
In some optional implementations of this embodiment, for a feature name in the at least one feature name, replacing a feature content corresponding to the feature name in feature data in the feature data set with a target feature content corresponding to the feature name. Namely, the determined target characteristic data is used for updating the characteristic data in the data sources of all types, so that the data synchronization function is realized.
With continued reference to fig. 3, fig. 3 is a schematic diagram of an application scenario of the method for outputting information according to the present embodiment. In the application scenario of fig. 3, the server receives feature data sets for the same object for different classes of data sources. The server then performs the following steps:
step 1, the position of the label 1 is a unified protocol management layer of each category, and is used for carrying out standardized management on feature data of various categories. The data access is followed by various categories of data source providers. The characteristic data acquired by the server is firstly processed by a unified protocol management layer and converted into a unified format. The location labeled 2 is the normalized feature data from various categories of data sources for a hotel in the map, including short comments, tags, status information, sub-point information, yellow-tag information, and the like.
Step 3, the position of the reference numeral 5 is merging processing, which is used for merging the results after the feature data of each category are transposed, and performing union processing on all categories with the same feature name, wherein the deduplication and sorting processing is not required. The position of reference numeral 6 is the output of the merging process, which is information based on all categories of each feature data. For example, different categories have respective short-term data, and the original data condition is as follows:
after a series of processing, the data format of the position of reference numeral 6 is:
step 4, the position of the reference number 7 is to select the target category to perform data fusion processing, namely reduction processing, and the reduction processing is divided into 3 types:
(1) priority control: if the feature corresponding to the feature name is exclusive, only one of all the categories is selected with the highest priority.
(2) Data merging: the feature corresponding to the feature name is shared, and all the category data can be subjected to data merging
(3) More complex operations: the feature processing corresponding to the feature name has more complicated control conditions and is completed by a function
The reduction of supported 3 types of processing can be completed through configuration, so that the labor cost is reduced. The position at reference numeral 8 is the output of the reduction, which is the data that will be directly available to the user of the future feature data, who no longer needs to develop a large amount of code for each category. The iteration efficiency of the whole data-related project is greatly improved.
According to the method provided by the embodiment of the application, the feature data sets from different types of data sources and aiming at the same object are subjected to data fusion processing according to the types, so that the fusion efficiency of data from different types of data sources is improved.
For example, the present application may enable the development period for category data exposure control requirements to be reduced from the weekly level to the hourly level. Can support 8 category requirements of indoor maps, vehicle life, scenic spots, authoritative data and the like. In addition, in practical application, 200 lines of original codes are developed in two modules respectively in order to process label display information of multiple types. For a total of 400 lines of code. After the reconstruction, the code with 400 lines can be replaced by only one line of configuration, and the efficiency is greatly improved.

Categories refer to categories of data sources. Such as indoor maps, vehicle life, scenic spots, authoritative data, etc. in the map data. Each category has a corresponding feature name. Such as short comments, labels, subtitles, icons, and the like. Each feature name has a specific feature content corresponding thereto. Data verification may also be performed prior to data processing. And verifying whether the category, the feature name and the feature content are included in the feature data. If any is missing, the feature data may be deleted. It is also possible to check whether the feature name in each piece of feature data is a pre-agreed feature name. The validity of the characteristic content, e.g. whether it includes reflexes, pornographs, can also be verified.
And 402, processing the deleted feature data set to obtain a key value pair set and a feature content table.
In this embodiment, the key-value pair set and the feature content table corresponding to the category may be generated separately for the feature data processing of each data source. That is, multiple sets of key-value pairs may be generated, each set of key-value pairs corresponding to a category. A plurality of feature content tables may be generated, each feature content table corresponding to a category.
Processing the feature data set comprises extracting categories, feature names and feature contents from the feature data. Then the category and the feature name are combined into a key-value pair. And storing the corresponding relation among the category, the feature name and the feature content in a feature content table. The feature content can be found through the category and the feature name. The diversified vertical data can be subjected to standardized management through a unified protocol management layer. And the data access is complied with by each vertical service party. The feature names and the feature contents are detailed data after each category is normalized, and include short comments, tags, state information, sub-point information, yellow tag information and the like.
